Simplify the following expression using properties of exponents.<br> (4z)⁻³×(2z)⁵
Elena-2011 [213]

Answer:

  z²/2

Step-by-step explanation:

The applicable properties of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

  (4z)^{-3}\cdot(2z)^5=(4^{-3})(z^{-3})(2^5)(z^5)=\dfrac{32}{64}z^{-3+5}\\\\=\boxed{\dfrac{z^2}{2}}

Cesar is 35 years old. He has $870 in a checking account, $2900 in a savings
mamaluj [8]

Answer:

A. $3770

Step-by-step explanation:

The correct answer must be $3770 (not $3270), checking accounts and savings accounts are liquid assets. However, cars are not liquid assets because liquid assets are things that can be quickly turned into cash without losing much if any of their inherent value. In this case, the retirement account is not a liquid asset as it is designed to hold your money until retirement age, and given that Cesar is 35 years old so he has not reached retirement age.

Find all the zeros of the equation.<br><br> -3x^4 + 27x^2 + 1200 = 0
pickupchik [31]

-3x^4 + 27x^2 + 1200 = 0

factor out -3

-3(x^4 -9x^2 -400)=0

divide by -3

x^4 -9x^2 -400=0

(x^2-25) (x^+16) = 0

x^2-25=0     x^2+16=0

(x-5)(x+5)=0      x^2=-16

x=5   x=-5           x = 4i   x=-4i

Answer:  x=5   x=-5           x = 4i   x=-4i
